Title: Storage of perishable animal and plant materials
IPC: A23L3/3409
Filed: 1963-03-26
Abstract: 1,005,612. Storing animal and vegetable materials. T. J. WILLIAMS (Whirlpool Corporation). March 26, 1963, No. 12006/63. Heading A2D. Perishable animal and vegetable materials subject to respiratory deterioration changes on storage in air containing normal quantities of oxygen and carbon dioxide, are stored in an atmosphere containing an amount of carbon dioxide greater than that found in ambient air and an amount of oxygen less than that found in ambient air, which atmosphere is continuously supplied from individual sources to a space containing the materials to be preserved and the escape of the atmosphere from the space is continuously permitted. Such atmospheres contain 1-10% by volume of oxygen, 1-15% by volume of carbon dioxide and an inert gas such as nitrogen, have 25-100% relative humidity (preferably 85-100%) and are maintained at a temperature of from 29‹ to 120‹F. (preferably 29‹-55‹F.). The gaseous constituents may be supplied from gas cylinders 14, 15 and 16 to a refrigerator 10; the humidity and temperature of the gaseous atmosphere introduced is regulated by a water bath 24, through which the atmosphere is passed, and evaporator coils 11, respectively. The atmosphere escapes through leaks diagrammatically illustrated by the passage 27. In a storage space subject to continual contact with the external atmosphere by repeated opening and closing of a door, it may be unnecessary to supply oxygen from gas cylinder 14. Animal and vegetable materials mentioned: apples, grapes, berries, tomatoes, peaches, pears, oranges and bananas; potatoes, carrots, celery, asparagus, onions, beans and peas; milk, butter, cheese and eggs; meat and meat products; grains, nuts, cut flowers, flower bulbs and tobacco.

Title: Improvements in or relating to artificial filaments, films and like articles, and processes for manufacturing the same
IPC: D01F2/28
Filed: 1929-04-18
Abstract: 310,045. British Celanese, Ltd., (Assignees of Dreyfus, C., and Whitehead, W.). April 21, 1928, [Convention date Void. [Published under Sect. 91 of the Acts]. Cellulose acetates and other carboxylates, process for making filaments and films from.-Cellulose acetate &c. artificial silk., films &c. exhibiting a complete or improved resistance to the delustring action of hot aqueous media, are obtained by employing in their manufacture solutions of cellulose acetate &c. containing either small or substantial proportions of an alcohol other than methyl alcohol, for example, ethyl alcohol in the form of denatured spirit. Thus, in the case of an acetone solution of cellulose acetate, resistance to delustring increases as the proportion of alcohol is reduced below 5 per cent or as it is increased from 10 to 40 per cent. Before solution, the cellulose acetate may have its moisture content reduced, by vacuum drying, to below 1 per cent. The process is applicable to wet or dry spinning; the latter is however preferred, the temperature of spinning being higher the greater the proportion of alcohol used. Forms made according to the present process may be woven or knitted with normal delustring yarns in order to give a variety of effects.

Title: Strengthening glass article and method
IPC: C03C21/00
Filed: 1966-03-21
Abstract: A silicate glass article, containing Na2O, and CaO and/or Al2O3 and/or ZrO2, is strengthened by contact with Ag+ ions so that Ag+ ions are exchanged for Na+ ions in a surface layer, thus inducing compressive stresses in the surface layer.  The compressive layer is at least 5m  and may be 100 m  or more in depth, and provides the article with an abraded strength greater than that of the untreated article. The amount of Al2O3 and/or ZrO2, if any, is not more than 5% by weight.  The ion-exchange temperature is above 200 DEG  C. and below the strain point; e.g., 50 DEG  C. below the strain point; suitable temperatures are e.g., 300-500 DEG  C. The article may be immersed in a bath of one or more molten silver salts e.g. AgNO3 or AgNO3/AgCl.  The glass may contain colourants.

Abstract: 592,965. Gas-blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. May 17, 1945, No. 12414. Convention date, May 20, 1944. [Class 38(v)] In an air-blast switch the moving contact is joined with an air-blast valve surrounding the contact close to the arc gap. Normally compressed air fills the switch, and the latter is opened by exhausting the space behind a piston 4, which is thus forced down away from a packing ring 2 in a fixed nozzle contact 1, and subsequently strikes a collar on the moving contact 3 to operate it. Alternatively, Fig. 2, the contact 3 may be rigid with the piston 4. The escape of air after the arc is extinguished may be limited by a piston 10 closing exhaust ports 6.
